FRANCIS H. RICHARDS, OF SPRINGFIELD, MASSACHUSETTS.

DEVICE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 333,161, dated December29 1885.

Application filed October 19,1885. Serial No. 180,366. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States,residing at Springfield, in the county of Hampden and State ofMassachusetts, have invented certain new and useful Improvements inMechanism for Converting Motion, of whichthe following is aspecification.

My invention relates to that class of devices in which continuous rotarymotion is converted into intermittent rotary motion; and it consists inthe combinations hereinafter described and claimed.

In the drawings accompanying and forming a part of this specification,Figure l is a longitudinal vertical section of a mechanism embodying myimprovements. Fig. 2 is a view of the under side of the same. Fig. 3 isan explanatory diagram.

Similar characters designate like parts in all the figures.

The operative parts of the mechanism are carried by a frame-work, A,having in this instance a box-shaped form, but of which the constructionmay be varied according to the circumstances under which the inventionisto be used.

S is the continuously-rotating shaft, supported in bearings 2 3. It isto be prevented from having longitudinal motion in said bearings bycollars or other suitable means not shown.

T is the intermittently-rotating shaft, standing about vertical to andabout in the same plane with shaft S. Said shaft T carries a disk-shapedwheel, WV, which is substantially a segment of a hollow sphere havingits center about at the axis of shaft S. The Wheel has a series ofequidistant slots, L, substantially radial thereto, whereby it isoperated. As shown in the drawings, said slots are five in number; butfour, six, or more maybe used equally as well.

The driving-shaft S carries a roller, (or pin,) P, at angle thereto,which angle is indicated at V, and is ordinarily about one-half theangle between two adjacent slots, L. Theroller has a stem, 6, which isadjustably fixed in a bracket, 13, rigidly attached to shaft S. The

bracket may, if preferred, be constructed as indicated by dotted linesat C, Fig. 1, and

placed outside of wheel W.

The roll P is, in practice, made tapering, and the slots coni'ormablyshaped for taking up any play arising from wear or otherwise. To effectthis, it is only necessary to loosen clamp-screw 7 and adjust stem 6 inthe bracket B.

The operation of the above-described mech anism will be readilyunderstood from Fig. 3. \Vheel W standing, as shown by solid lines, theroll enters a slot at 8, passes on, as indi cated by circle 9, to itsuppermost position 10, and then to position 12, thus turning the wheelthrough one division, and bringing the next slot to position 8, readyforthe next turn of the roll. 7

In Figs. 1 and 2 the roll is shown at position 10, positions 8 and 12being shown in Fig. 2 by dotted lines.

When running at low velocities, the wheel may usually be relied on toremain at rest while disengaged from the roller; but sometimes aholdfast apparatus maybe required. For this purpose the wheel may have aseries ot'notches, 13, into which a bolt, 14, may be forced by cam 15 atthe moment when said wheel has completed its motion. WVhen the wheel isabout to move, just as roll P enters slot L, the bolt may be withdrawnby a spring or by the cam.

Having thus described my invention, I claim 1. The combination of wheelW, substantially of the form of aspherical segment, having a series ofslots, and shaft S, having a roll set inclined thereto and working insaid slots, all arranged substantially as described, and for the purposespecified.

2. The combination of wheel W, having slots L, shaft-S, bracket B, stem6, adjustable in said bracket, and the tapered roll P, substantially asdescribed, and for the purpose specified.
